I have used seafoam before on other vehicles by adding it to the brake booster line and i smoked up and its thing. I added it to my f 150 right into the brake booster line and it didn't smoke nothing happened. What do you suppose that means?

When I did mine it smoked up my hole back yard.

Yeah see!!! I've done it to other vehicles and other trucks and it smoked like crazy. I do to my truck and nothing I swear nothing I could just kinda smell it I think
I wanna know if that's good or bad

I have no clue. I had to wait about 10 minutes before it would quit smokin. I used 3/4 of the bottle slowly while it was running and it wasn't smokin. Then had my wife come out to turn ignition off if the last 1/4 didn't stall it, when I dumped it in. Then I let it sit for about an hour. But when I started after it smoked up a storm. Did you let it sit for alittle?

Just means there was more IPA in that can than Naphtha. Read post 11 here to learn the chemistry of how seafoam "works" and what the smoke is.

I had seafoamed my truck a couple times before. This time I poured a little more into the brake booster than last time and let it sit for a couple hours. It smoked more this time than the last 2 times combined. My truck was feeling kind of sluggish before. After I used it I could tell the power was restored some. I think it has as much to do with how long you leave it in as anything. It works good for me. People will try saying it doesnt work, but I have had good experience with it.
